DEVICE FOR FORMING LOOPS IN TERMINAL WIRES FOR ELECTRIC LAMPS.

SPECIFICATION formingpart of Letters Patent No. 263,622, dated August.29, 1882.

Application filed July 20, 1882. (No model.)

To all whom it may concern:

Be it known that I, ALFRED SW'AN, a subject of the Queen of GreatBritain, and resid in g in the borough of Gateshead, in the county ofDurham, England, have invented Improvements in Apparatus for BendingLoops or Eyes in the Terminal Wires for Incandescent Electric Lamps,(for which I have obtained a patent in Great Britain, No.2,898, dated19th June, 1882,)xof which thefollowing is a specifi- My inventionrelates to improvements in apparatus for bendingloops or eyes in theterminal wires for incandescent electric lamps for the attachment of theconducting-wires and Figure l of the accompanying drawings represents inplan, and Fig. '2 in side elevation, an apparatus for this purposeconstructed according to myinvention. Fig. 3 is an enlarged plan ot' apart of the same. 7

Upon a bed-plate, h, I fix a stop-piece, k of the form shown, and abutton, 7L3, which may shown at h, to retain the wire loop in position.In a framing, i, beneath the bed-plate h, are carried spindles i i 43 tfurnished with gearing-wheels for transmitting motion to bothof thespindles t i when the button on the spindle t" is rotated. The spindlesi and i project above the bed-plate h, as shown, on either side oftheend of thestop-piece 7L2, the distance between the axes of the saidspindles being equal to that required between the centers of the loopsto be made in the wire. The projecting ends of the spindles d t areformed with slits or recesses, which may be made either by cuttingthemin the substance of the projecting ends of the spindles or by pins 6placed near to the said projecting ends, as shown. The

wire bent into the U form shown in Fig. 4 is Patented in England June19, 1882, No, 2,898.

placed around the button It, wit-h its legs or side pieces lying alongthe sides of the stop, and the two ends of the said wire are placed inthe slits or recesses in the projecting ends of the spindles t i asshown in full lines in Fig. 3. On partially rotating the spindle i bymeans of the button the gearing-wheels cause also the spindles i '5 "ito partially rotate until prevented from further rotating by the stop7L2, so that the spindles i i are brought into the position shown indotted lines in Fig.3, and by this partial rotation (as the ends of thewire are confined in the slits or recesses in the ends of the saidspindles) the said ends of the wire are bent into a loop form, as shownin dotted lines in Fig. 3, and also in Fig. 5,which represents a bentwire removed from the apparatus, short tags or ends being formed, as atj, which tags or ends serve to effect the secure attachment of the loopsto the glass when they are subsequently embedded therein.

I claim as the invention- The hereinbefore-described apparatus 'forforming loops or eyes in the terminal wires for incandescent electriclamps, the essential fea ture of which apparatus is the combination ofthe rotating spindles i i, recessed or slotted or otherwise formed forthe reception of the ends of the wire to be.bent into loops or eyes withthe stop 7L2 or stops 7:? h as hereinbefore described and illustrated.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALFRED SWAN.
